CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 349,726, datedSeptember 28, 1886.

Application filed December 11, 1885. Serial No. 185.395. (No model.)

the coupler to be readily detached on any grade, and thus enable thetrain to be cut in two when moving on upgrade or making a flying switchwithout necessitatinga slackening of speed.

A further object is to provide detaching and automatic coupling devicesthat shall be simple and durable in construction, of small initial cost,and adapted to be applied or combined with draw-heads, so that they maybe used in connection with cars furnished with the ordinary links.

With these ends inview my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of the draw-heads of'two adjacent cars provided with my improved coupling. Fig. 2 is an endview of one of the couplings, partly in section. Fig. 3 is alongitudinal section of the two couplings when connected. Fig. 4 is aperspective view of one of the couplings, and Fig. 5 is a modified formof lock-bar.

A A represent the draw-heads of two adjacent cars, each provided with myimprovement. As the draw-heads are similar in construction, I willdescribe one of them only.

Draw-headAis constructed with the flanges B and 0, formed on each sideof the recess D,

by means of which lateral displacement of the opposite draw-head isprevented, the forward portion of the draw -head forming a guide, E.Within the draw-head is formed a socket, F, in the rear of which ispivotally secured the locking-jaw G by means of a vertical bolt, H,secured in the head. The jaw is provided with thelaterally-projeetingshoulder I, the forward portion of which is beveled, as shown,whereby the jaws upon opposite draw-heads are conveniently forced intothe interior of the recess D, and the inner edges of the shoulders I areclamped in position. Extending through the outside ofthe drawhead andopening into the socket F is formed the slot or opening J, through whichpasses the arm K,- secured to the rear of the lockingjaw G, or formedintegral therewith, as preferred. The outer end of said arm is pro-Vided transversely with the perforation L, adapted to receive a link, M,or other connecting device attached to the gravity-bar N, the said barbeing 'pivotally secured betweenthe arms 0, formed integral with thedraw-head at or near the top thereof. The inner end of the gravity-bar Nis beveled downwardly and inwardly, as shown, and the link or connectingdevice M is attached thereto in such manner that when the bar isadjusted horizontally relative to the draw head the shoulder I is drawnwithin the socket F. Near the center of the gravity-bar is pivotallyattached the rod P,which extends to the top of the car, and is providedat its upper end with the handle I Q. To the top of a car, or nearthereto,-is secured a rest, R, provided at its outer end with a hole, S,through which passes the rod P. The bar is loosely mounted at its lowerend in a suitable socket, which will permit the bar to be rotated. Therest R is provided with a hook, S, to which one of the arms, T, of thebar is secured when it is desired to elevate the gravity-bar and preventthe operation of the coupling devices.

When in use upon platform-cars, the car may be provided with asuitablehoolgand the lower arm can be used to secure the rod in elevatedposition. When it is desirable to dispense with the rod P. thelocking-jaw G can be locked out of possible action by inserting apinthrough the perforation U, formed in the arm K.

When the cars are coupled, by raising the rod P, the gravity-bar N iselevated and the locking-jaw G will be drawn. into the socket F, therebydetaching the couplings. When the rod P or gravity-bar N is lowered, thelower beveled end thereof will bear against the end of the arm K,thereby forcing the locking-jaw out of the slot, and the sameis readyfor adjustment.

In the modification shown in Fig. 6 the draw-head is provided with therecess D and the flangesB and C, by means of which lateral displacementis prevented. The guideframe a, is provided transversely with theverticallyelongated slot 12, in the rear of and adjoining which issecured the laterally-extending bracket 0, the head d of which isprovided with the vertically-elongated slot 6. A locking-jaw, f, islocated in the said slots 12 and e, and is secured to a gravity-bang, bymeans of the arm or pin h, which is rigidly secured thereto, the saidpin passing through the elongated slot t,

v formed in the side of the bracket 0. The gravity-bar g ispivotallysecured to the side of the bracket, and is loosely attached tothe pin h by means of the vertically-elongated slot j, formed in thepivoted end of the bar.

The action of the modified form is similar to that described in thepreferred construction, and the same can'also be provided with rod P,adapted to be operated as described.

By my improved car-coupler the cars may be automatically coupled withoutrequiring the-brakesman to enter between the cars, as the locking-jawsare in constant adjustment unless otherwise placed. The cars can beconveniently uncoupled from either side or from the top.

As it is evident that many slight changesin the construction andrelative arrangement of parts might be resorted to without departingfrom the spirit of my invention, I would have it understood that I donot restrict or limit myself to the exact construction and arrangementof parts shown and described.

I am aware that it is old to provide a drawhead with a bell-crank leverpivoted at its elbow Within the coupler, and provided at one end with anarrow-head forengaging a similar device on the adjacent draw-head and atits opposite end with a weight; and also that it is old to construct adraw-head with projecting parts for engaging correspondingly-shapedrecesses in the adjacent draw-head, and with a pivoted jaw for engagingthe jaw of said adjacent draw-head, and hence I make no claim, broadly,to such constructions.

Having fully described my invention, what I Patent, is

1. In acar coupling, the combination, with a draw-head and locking-jawsecured thereto,

of a gravity-bar pivotally secured to said drawhead and pivotallyconnected with the jaw, whereby the same is automatically locked,substantially as set forth.

2.' In a car-coupling, the combination, with a draw-head having a slotformed in one side thereof, of a locking-jaw pivoted in said slot and agravitybar pivotally secured to said drawhead and pivotally connected tosaid jaw, whereby the jaw is automatically locked, substantially as setforth.

3. In a car-coupling, the combination, with a draw-head and aslot orrecess formed in the guide-bar thereof, of a jaw pivoted in said recess,an arm formed laterally on the jaw extending through said guide-bar andpivotally connected to a gravity-bar, whereby the jaw is automaticallylocked, substantially as set forth.

4. In a car-coupling, the combination, with a draw-head having a recessor slot formed therein, of a locking-jaw pivoted in said recess andpivotally connected with a gravity; bar and means for locking the jawout of possible engagement, substantially as setforth.

5. In a car-coupling, the combination, with a draw-head and alocking-jaw secured thereto, the said jaw having a laterally-extendingarm through said bar, of a gravity-bar pivotally secured to said arm,and an upright rod pivotally secured to the bar, and means forlockingthe rod in vertical adjustment, substantially as set forth.

6. The combination, with a draw-head provided with a side extension, ofa lock'bar pivotally secured in said extension and a gravity-bar forautomatically throwing the lock-bar into locked adjustment,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

DAVID LIPPY.
